Mumble 1.3.2 is a maintenance release that fixed overlay not starting, and keychain-error on macOS for custom certificates.

How to Install Mumble in Ubuntu:

Mumble is available as containerized Snap and Flatpak packages. You can install the Snap from Ubuntu Software, and install Flatpak from flathub repository.

For those prefer .deb package from apt repository, do following steps to install it from Mumble Team PPA.

Don’t know why, the PPA so far does not support Ubuntu 20.04. You can however CLICK HERE download the Ubuntu 19.10 eaon package, “mumble_1.3.2-1~ppa1~eoan1_amd64.deb”, which installs and works very well in my case.

Just download the package and install via command:

cd ~/Downloads/ && sudo apt install ./mumble_1.3.2-*amd64.deb

1. Open terminal either from application menu or by pressing Ctrl+Alt+T on keyboard. When it opens, paste below command and hit Enter:

sudo add-apt-repository ppa:mumble/release

Type user password (no asterisk feedback) when it prompts and hit Enter to continue adding the PPA.

2. If an old release was installed, simply upgrade Mumble via Software Updater:

Or run commands one by one in terminal to check updates and install the chat utility for gamer:

sudo apt-get update

sudo apt-get install mumble mumble-server

Uninstall Mumble:

You can purge the PPA which also downgrade the VoIP chat app to the stock version via command:

sudo apt-get install ppa-purge && sudo ppa-purge ppa:mumble/release

To simply remove mumble, either use system package manager or run command in terminal:

sudo apt-get remove mumble mumble-server
